$10x^3+x-1$

Well, we need to combine like-terms and simpllify the inequality. I do that using the system shown below:

$color(white)(..)6x^3-7x-4$
$+$
$color(white)(..)4x^3+8x+3$
$color(white)()$ ----------------------------------
$color(white)(..)10x^3+x-1$

You can do this any way you want, but the key is to combine like terms.
